Facebook Block

I go on my FaceBook Page and go to my Chat Window Settings.
I click the Gear Icon for the Options Menu.

Then I Click Turn Off Active Status.

And a Window opens and I pick Turn Off Active Status For All Cantacts.

I Click OK and go off.

But when I go back I check my Options it put it back to the Settings it was on.

How do I do this???

 

Thank you for getting back to me.
I use Win7. and FireFox.

I do not use any Cleaner Program.
But thanks anyway.
